Definitions
- the invention concerns the propulsion of boats. It is a well known fact that auxiliary engines for boats operate with their own transmission systems-between engine shaft and propeller shaft, though -this obviously involves considerable drawbacks for reasons of cost, bulk and manoeuverability.
- Subject of the invention is a system for propulsion of boats having one or else two marine combustion engines and tumbler gears.
- the system comprises an auxiliary engine kinematically connected to the shaft of one or of the two engines connected to the propeller shaft.
- the boat can be driven even if there is failure of one engine or of the tumbler gears, or if the boat is used for trawl-line fishing that requires a speed which may even be less than two knots.
- Kinematic connection between the shaft of the auxiliary engine and that of a main engine is made by means of a hydraulic motor mech- 0 anically connected to the shaft of the main engine and hydraulically, , . by. two-way tubes, to a hydraulic pump kinematically connected to the shaft of the auxiliary engine. .. '
- Mechanical connection between the shaft of the hydraulic motor and " that of the main engine is made by pulleys fitted onto the shafts. and connected by continuous belts. - . .
- Hydraulic connection between the hydraulic motor and the hydraulic pump is made by two-way tubes.
- the shaft of the auxiliary engine is also kinema-. i. ⁇ tically connected to a power take-off point on ttie main engine. 0
- This kinematic connection between the shaft of the auxiliary engine a ⁇ d the power take-off on the main engine is made. by. pulleys fitted respectively onto the shaft of the auxiliary engine and onto that of the power take-off on a main engine and connected by continuous belts. 5
- the system offers evident advantages.
- auxiliary engine brought into use if there is failure of the main engine or tumbler gears, direct connection can be made with the propeller shaft fitted to the engine shaft, providing considerable benefits as regards costs, weight and manoeuverability of the 0 boat, there being no need for a propeller shaft for the auxiliary engine, and no interference with the characteristics of dynamic thrust generated by the shaft of the damaged engine.
- the shaft of the damaged engine can be rotated so that the boat is kept perfectly under control.
- the auxiliary engine permits propulsion at low speed, replacing the trolling valve but also avoiding the frequent risk of failure of the tumbler gear which can happen if the easily forgotten trolling valve is left in the 'on' position.
- the auxiliary engine can be installed anywhere in the boat in view of its versatile connection by means of tubes. Characteristics and purposes of the invention will be made still clearer by the following examples of its execution illustrated by diagrammatically drawn figures.
- Fig. 1 System of propulsion for boats, side view.
- FIG. 2 As in Fig. 1 , perspective view from above.
- Fig. 3 As above showing the power take-off.
- Figure 1 shows the system of propulsion 10 with main marine Diesel engine 11 , propeller shaft 12 and propeller 13.
- the system comprises the auxiliary marine Diesel engine 30 with its shaft 31 onto which the hydraulic pump 35 is fitted.
- Said pump 35 is connected to the hydraulic motor 20 on support 28 by means of the tubes 40, 41.
- the pulley 22 with races 23 fits onto the shaft 21 of said hydraulic motor 20.
- the pulley 24 with races 25 fits onto the propeller shaft 12 of the main engine 11.
- Said pulleys 22, 24 are joined by continuous belts 27.
- FIG. 3 illustrates a complementary addition 45 to the system 10 consisting in connection of the shaft 31 of the auxiliary engine 30 to the power take-off 15 on the main engine 11 by means of the pulley 50, with races 51 , fitted onto said power take-off 15, and of the pulley 55, with races 56, fitted onto the shaft 31.
- the two pulleys 50 and 55 are connected by continuous belts 57.
